UNITED STATES PATENT OFFICE.

VALVE-SEAT FULLER.

Application filed September 8, 1925.

To all whom it may concern:

Be it known that I, HENRY E. Jonny, a citizen of the United States, residing at Huntsville, in the county of alker and State of Texas, have invented certain new and useful Improvements in a Valve-Seat Puller, of which the following is a specification. A

This invention relates to new and useful improvements in a valve seat puller.

One object of the invention is to produce an implement of the character described specially designed for the purpose of unseating and pulling valve seats.

Another object of the invention is to provide an implement of the character specified specially designed for pulling the valve seats of slush pumps, and for similar purposes.

A further feature of the invention is to provide a device of the character described which is of simple construction and may be cheaply produced and easily and effectively operated.

IVith the above and other objects in view this invention has particular relation to certain novel features of construction, operation, and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings wherein Figure 1 shows a side view of the puller, as applied to the work, and shown partly in section.

Figure 2 shows a cross sectional view, and

Figure 3 shows an edge view.

Referring now more particularly to the drawingswherein like numerals of reference designate similar parts in each of the figures the numeral 1, designates the pump body having a ring like valve seat 2 seated therein.

The puller includes a rod 3 pivoted on 0pposite sides of one end of which are the Serial No. 55,046.

puller bars 4, l, whose ends are notched in wardly, forming the shoulders 5, 5. The 0pposite end of the rod, 3 is fitted through a central bearing 6, of the yoke 7, and outwardly threaded. A nut 8 is threaded onto the threaded end of the rod and interposed between it and the yoke, and carried by the latter, are the anti-friction bearings 9.

In application to the work the yoke 7 and nut 8 are removed and. the bars 4 are inserted through the seat to be pulled and the shoulders 5 then engaged under the seat.

In order to hold the device in place, while the yoke is being replaced, there are the yieldable hooks 10, 10 which are attached to the cross rods 11, 11, connecting the bars 4, by means of the coil springs 12. These hooks are adapted to be engaged over the seat in Figure 1, for the purpose stated.

The yoke 7 is then fitted over the rod 3 and rests on the pump body and the nut 8 is then applied. By the application of a wrench to said nut a pull may be exerted, through the rod 3, and the seat 2 thus unseated and removed.

What I claim is 1. A valve seat puller including a pull rod, a pair of seat engaging bars pivoted to one end thereof, a yoke mounted on the rod, a nut threaded on the rod and adapted to abut said yoke, means adapted to engage over the seat to hold the puller in proper relation to the seat. 7

2. A valve seat puller including a pull rod, a seat engaging bar pivoted to one end thereof, a yoke fitted over the rod, a nut threaded onto the rod and adapted to abut the yoke, and yieldable hooks associated with the device and adapted to engage over the seat to be pulled.

In testimony whereof I have signed my name to this specification.

HENRY E. JORDY.
